Raisa Cole takes to Jo'burg's streets to find out why most of us don't use public transport.

The transportation sector is the most rapidly growing source of greenhouse gases in South Africa. According to the United Nations Framework Convention on Climate Change (UNFCCC) the carbon emissions from the sector has grown by 30% in the last ten years, making it the fastest growing sector in terms of carbon emissions.

Reducing the number of cars on the road seems to be the logical answer, but the majority of South Africans still use private vehicles as their primary mode of transport.

The power of the bicycle was palpable in Cape Town (two weekends ago). It was inspiring to see the Argus Cycle Tour energy overtaking the city as usual. Even more exciting was to see hundreds of concerned citizens join the Cape Town leg of the World Naked Bike Ride on Saturday morning in a call for safer cycling, and sharing through their painted bodies important environmental and social concerns. (The World Naked Bike Ride is an international event driven by cyclists who meet and ride together to "deliver a vision of a cleaner, safer, body-positive world.”) What may seem to some as an eccentric event highlights the burning desire on the part of citizens to promote a bicycle friendlier-city and a more sustainable place to live.

Is your New Mobility project moving minds as well as people? Then enter the SMART Mobility EnterPrize competition and you could find yourself moving in new mobility circles at Rio+20, and beyond.

New Mobility – also known as ‘sustainable transportation’ – is about moving people, moving goods, and moving less, in ways that are cleaner, greener, safer, healthier, and more equitable (and more ‘hip’, of course…).

One Struggle – a conference on social justice, animal rights and radical environmentalism - took place in Muizenberg last Saturday (18 Feb) thanks to the South African Vegan Society.

The conference focused on the rights of animals, the environment and human beings.

Hearing about the One Struggle conference, I was immediately excited; the South African Vegan Society represent a genuine passion for true authentic societal change, and I knew this would be reflected in any event they organised.

When we arrived in the afternoon, Jodi Allemeier was busy giving her talk on veganism and food security in Cape Town: explaining how being vegan is better not only for animals, but for people and the earth too. The young lady really sounded like she knew her stuff, and displayed all the facts to back up her statements.

‘We may be making attempts to save water in our home due to turning off taps and showering instead of bathing, but when 85% of our water waste is on our plate it is important that we re-evaluate our diet. And this is not mere theory – the U.N. have been urging people to eat local and plant-based for years,' she explained, adding: 'But it is not just our diet that must change, but the production system of our diet.’

City Sightseeing Cape Town, the company that operates the well-known red double decker open-top buses has become the first bus company in South Africa to be certified carbon neutral.

City Sightseeing operate a fleet of continually upgraded, low emission buses that comply with all Euro standards for environmental impact. The fleet has consistently complied with Euro standards since 2006.

City Sightseeing has also made great inroads into greening the rest of the business and has adopted all the latest available methodology and technology to reduce noise pollution as well as energy and water consumption. The company also recycles all of their waste, which has in turn led to the creation of sustainable employment.

pedestrians make use of the new paths in Durban: pic by Luke ReidRapid transit and safe cycling/walking networks are good for both health and climate - and climate experts should consider more systematically how these strategies can reduce CO2 emissions in the transport sector, one of the world's major contributors to climate change, says a new WHO report.

The report reviewed over 300 studies on health outcomes from different types of land transport systems to identify those mitigation measures most closely associated with specific health co-benefits or risks.

In Cape Town, we are fortunate to have one of the most prolific upwelling systems off the South African coastline. This creates an ideal environment for

Running concurrently with the Green Expo this weekend (18th - 20th Nov), the Cape Town Climate Change Coalition is hosting a gathering called Inspiring Change.

Held at the Cape Town International Convention Centre (CTICC) from 18 – 20 November 2011, this series of talks and demonstrations aims to stimulate fresh thinking and to share ideas about our city.

The gathering includes several cool aspects including the Siemens electric mobility roadshow, Pecha Kucha sessions, inspiring panellists deliberating on Cape Town's role in climate change solutions, site visits and a Carotmob.

The travelling exhibition by Siemens has already been in many parts of the world and makes its

It might be old news and becoming a bit repetitive, but yes, really think about when you use your car and why. Could you walk or cycle to where you need to be? Why not take a train or bus? (The Gautrain is fantastic and Cape Town’s MyCiti bus system is reliable and affordable).

Slow down Schumacher!

Speeding is probably the most common way the majority of us use excessive amounts of fuel. In many

With most of the worlds population now living in cities, it is no news to say that traffic congestion has become a huge urban problem, as is the pollution and accidents caused by motor vehicles. With the added fear of climate change and peak oil, there has arisen an urgent need for a social shift towards more sustainable mobility use.

The City of Cape Town recognises October as "Transport Month" and last week hosted a couple of events focussing on Public Transport Interchanges (PTI).
